CLOSURE FOR-THE OPENINGS 0F CONTAINERS.

To all whom it may concern Be it known that we, Louis Brown and LEONI-IARD BAUROTH, citizens of the United States, and residents of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Closure for the Openings of Containers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Our invention relates to closure means for the openings of metallic packages andment of the parts of the invention are fullyv described in the following specification, and while the invention in its broader aspect'is susceptible of numerousmodifications, a preferred embodiment of the same is illustrated in the accompanying drawings, in

Figure 1 is a plan view of a closure embodying the invention with the split locking-ring contracted. Fig. 2 is a partial central longitudinal section of the upper portion of a package with a closure set in the opening thereof but not locked against removal. Fig. 3 is a side elevation of the same with .a portion in section and the closure shown as locked against removal, and Fig. 4 is an enlarged section of a portion of the package and closure in locked engagement.

Referring to the drawing, 1 designates the side casing or wall of a sheet metal package, such, for instance, as a keg or the like, an end of which is providedwith an opening, preferably round, for the reception of a closure-member 2 of sheet-metal, which opening may be coextensive with the end of the package, as shown, or of less diamepressure on the closure.

of the casing 1, which forms the wall of such opemnjg in the present instance, is headed, as at 3, around a reinforcing wire with a portionof the bead disposed on each side of the casing to provide inner and outer annular ribs or shoulders thereon.

The closure 2 is drawn in pan-shape to i adapt it to fit within the package opening with its side wall 4 in frictional contact with the inner side of the head 3 and the outer edge thereof rolled outwardly and downwardly, as indicated at 5, to adapt it to hook over the head. After the closure has been inserted into the opening the lower or inner portion of the side wall 40f the closure is under the inner edge of the rib or shoulder formed within the casing by the head 3 to prevent a withdrawal of the closure" from the open1ng, a is apparent by reference to F1gs. 3 and 4. p

The closure wall 4 having been expanded to cooperate with the head 3 to retain the closure in the package opening, a split spring-ring 6 is sprung within the annular groove thus formed within the closure and efiectually serves to prevent a contraction of such expanded portion, which might otherwise occur under the stress of internal The rod or band forming the ring 6 is preferably of suitable length for its ends to meet, or substantially so, when sprung within its receiving groove in the closure so thatv the abutting contact of such ends will resist a contraction of the ring. If desired the ends of the ring may. be provided with a tongue and a groove complemental to each other, as shown at 6 Fig. 1, which interlock when the ring is sprung. in place within the closure.

The outer edge 7 of the closure wall 4 is preferably, but not necessarily projected below the head 3 to adapt it to be drawn under the same in opposition to the expanded portion of the closure, as shown in Figs. 3

and 4. A binding-Wire 8 is then drawn tightly around the contracted edge of the closure and may have its ends twisted or otherwise secured together, as indicated at 9 Fig. 3, thus cooperating with the bead 3 and spring-ring 6 to securely retain the closure to its seat in the opening.

The bead 3 is preferably formed by rolling the end edge of the body. wall 1 outwardlylaround a core wire, which has its ,and varying stresses to which they are subjected, is due very largely to the co6perative action of the several parts employed, as the ring 6 cotiperates with the interposed layers of metal to resist the compressing action of the band 8, and vice versa, and the rigid construction of bead, which forms the inner and outer ridges, cooperates very materially with the members 6 and 7 and the side Wall of the closure to provideapackage the chime portion of which is of the strength required to stand the tests to which such packages are subjected.

It will be apparent that we have not only provided a closure which is exceedingly strong and durable in its construction and simple of application, but one which forms a close and air-tight joint with the wall of the opening and is therefore adapted for use in any connection in which sealed joints are essential.

We wish it understood that our invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described our invent-ion,what

' we claim as new, and desire to secure by cocperating with each other and with the head ring to form a rigid chime.

- 2. A container of the class described hav-- ing an end edge of its body wall beaded to form its chime with an internal and exter nal ridge, a pan-like closure fitted into said chime with its bottom disposed below the chime ridges and having its side wall embracing said chime with opposing portions dr'awn under the respective ridges in opposing contact with the container wall, anexpanding ring disposed within the closure and seating within the expanded portion of the closure under the internal ridge, and a ring-like hand drawn closely around the inwardly drawn portion of the closure .wall whereby said expanding ring and band cause the portions of the closure wall against which they respectively seat to be held in opposing contact with the container wall below the edge bead thereof.

In testimony whereof we' have hereunto signed'our names in the presence of two subscribing witnesses.
